The activities and cognitive functions of the brain, which mostly originate from the activities of the central nervous system, are the building blocks of human behavior and decisions. Among the cognitive functions are attention and memory, which according to previous research, a direct relationship between these two activities has been reported. One of the senses affecting human attention is vision and it is considered as an input for visual attention. The reception of human visual signals is processed by the eye, and eye movements, along with the characteristics of the received image, affect attention and memory. In previous researches, the relationship between emotional image stimuli and the characteristics of negative emotions has been investigated in the axes of the two-dimensional model of emotions, memory, and eye movements. This effect has been reported as memory bias and the reason for it has been identified as an increase in the recall of immune system stimulating factors in the body. In the current project, using Eye-Tracking techniques, the effect of emotional stimuli with positive emotions on memory has been investigated. The effective features of eye movements in this project have shown the level of memory and attention, and the amount of difference in the stimuli recall and the amount of memory bias have been evaluated using recall tests. 56 subjects participated in this experiment, and in each session, a set of Eye Tracking task, a memory questionnaire, and an emotion level questionnaire were performed. It should be noted that the stimuli used in this experiment were made using diffusion artificial intelligence models, and the ability of these models to create cognitive deviations of the brain and the possibility of using this method as a memory aid are also evaluated. According to the results, the hypothesis of memory deviation using positive emotional stimuli was accepted and emotional stimuli with positive arousal and valence levels had more recall than emotional stimuli with normal arousal and valence levels. On the other hand, this difference is also observed in the features of eye tracking and optimal search of the brain.
